# Overrides for mailcow-dockerized

Provides files that are meant to be copied into your location of the [github.com/mailcow/mailcow-dockerized](https://github.com/mailcow/mailcow-dockerized) repo thereby customizing its behavior.

yq 'del( .services.[].environment.[] | select(. == "TZ=*") ) | del(.. | select( (tag == "!!map" or tag =="!!seq") and length == 0)) | del( .services.[].restart )' /opt/containers/mailcow-dockerized/docker-compose.yml | yq --indent 4 ea '. as $item ireduce ({}; . * $item )' - /opt/containers/mailcow-dockerized/docker-compose.override.yml > /opt/containers/mailcow-dockerized/docker-compose.final.yml


* Env variables
    ```
    yq 'del( .services.[].environment.[] | select(. == "TZ=*") ) | del(.. | select( (tag == "!!map" or tag =="!!seq") and length == 0))' ...
    ```
    From all `.services.[].environment.[]` lists remove items that match the expression `TZ=*`. Realistically this removes the `TZ` environment variable declaration and in some cases leaves the `environment` list empty. If the list now truly is empty delete it.

    Given a file:
    ```
    services:
        unbound-mailcow:
            image: mailcow/unbound:1.16
            environment:
                - TZ=${TZ}
            volumes:
                - ./data/hooks/unbound:/hooks:Z
    ```
    Step one does:
    ```
    services:
        unbound-mailcow:
            image: mailcow/unbound:1.16
       ---> environment:
            volumes:
                - ./data/hooks/unbound:/hooks:Z
    ```
    We detect that `environment` is now empty and delete it:
    ```
    services:
        unbound-mailcow:
            image: mailcow/unbound:1.16
       ---> volumes:
                - ./data/hooks/unbound:/hooks:Z
    ```
* Restart policy
    ```
    del( .services.[].restart ) ...
    ```
    From all services delete restart policy declaration. We're defaulting to `unless-stopped` via the `extends:` directive.
